| The path of the Mars flyby of C/2013 A1 gets narrowed down putting it slightly closer to Mars, but the impact probability continues its drop from the first estimates.

| Quote (PlanetExplorer12) I sadly have never seen a comet, but i've seen a meteor shower before. Which was the last naked eye comet, it wasn't very long ago? McNaught? That was in 2007. This is an f/8 ISO200 2 sec exposure using 500mm:
Edit: There was another comet in 2007, Holmes. Less spectacular, I think. Here's a dual exposure (moon for size comparison - in reality they were far apart):
Same focal length used for both exposures (1500 mm). f/11 and 2.5" for the comet and 1/200" for the Moon.

That one I saw. Looked pretty cool through binocs or a small scope.

| Hale-Bopp in the mid 90's was epic. Possibly once in a lifetime (but lets give Ison a chance). I don't think I photographed it, though. My scans before 1998 are incomplete.
Shoemaker-Levy was a big event as well. And a big internet event.

| Quote (HarbingerDawn) I wasn't aware of the existence of the internet until 1995 You belong to the September generation, then.
I began at the university in 1992. The internet was ftp, telnet, gopher, archie, MUD, etc, but in 1993 the Mosaic web browser appeared and so did a lot of web sites and soon a few search engines (well, in the beginning there were just index sites, mostly manually updated), which transformed everything. Events like Shoemaker-Levy certainly raised awareness.

| Yeah, it seems like it hasn't dropped a magnitude for the last 3 months. I've been hoping some comet experts would say something about what they expect from this, but it's probable that it's still just too early to tell.

| They're probably only going to say that comets are unpredictable.
